Export and run script

Description

I use Proxyman extensively to capture traffic, which then gets analysed by other tools (some I build, some 3rd parties).
Currently, this requires exporting the requests I'm interested in, exporting them to file (just the response body, or the whole request) or as archive (HAR or Proxyman), then running my CLI tools passing those files paths as argument.

I would like to suggest a new feature that makes it possible to have all that done automatically, through

1. a mechanism to register commands in Proxyman
2. within which placeholders can define what type of file I want to have
3. right click > export > script >
4. Proxyman exports the selected requests in a file in the format defined by the placeholders, and runs the command with it, then displays the STDOUT of that command

This likely requires being able to set an environment for running the command, in particular: working directory, environment variables, etc.

For example:
Name: "analyse MPD"
Working directory "~/Analyses"
Command: "uv run python analyse.py {{response_body}}"

I'm sure there are tons of side cases I'm not considering (eg. what if multiple requests are selected, and placeholder {{response_body}} is used (instead of for example {{har}})? Run the command for each of them? Block?
I'm open to any discussion.

Why this feature/change is important?

Faster ability to run workflows directly from Proxyman
